FEED-Vt/ATER HEATER AND FUEL-SAVER.

' To aZZ whom it may concern:

. exact description of the invention, which will obviated.

enable others skilled in the art to which it appertains to make and use the same.

Our invention consists of a boiler feed Water heater whereby an enormous saving in consumption of fuel is accomplished. The apparatus is placed in the smoke box of a locomotive or engine and fastened to that portion of same, where the exhaust steam pipe opens into the smoke box, and may be made of a size to correspond with that of the locomotive or engine in which it is intended to be used, having regard to the height of the boiler tubes. It is fastened over the exhaust steam pipe, at a distance of about ten to twelve inches from the boiler tube ends, so that the draft is not lessened. The water is conveyed from the pump or injector by means of a pipe and check valve to an upper chamber of the apparatus, from which it flows into tubes, placed vertically with intervening spaces. The water flowing through these tubes empties into a second or lower chamber, and a perfect circulation is thereby gained, and is then discharged into a pipe which is bent round the smoke box, and carried to a valve emptying into the boiler. The action of the pump or injector forces the feed water direct from the tank through the apparatus to the boiler. The liability of a pump or injector to stop Working through becoming heated is thereby The apparatus is used and acts as a continuation of the exhaust pipe. The steam from the exhaust passes right through it finally escaping at the top, and at the same time, the heat, flame, 850., from the ends of the boiler tubes play upon the outer casing, and this combined with the use of the exhaust steam in manner specified, imparts heat to the water flowing through the apparatus, to the extent of not less than three hundred degrees, and thus instead of feeding the boiler with cold water, you have it running in at a great heat.

The apparatus. is provided with suitable connections for the inlet and outlet of the water. The number of tubes contained may be in accordance with the size, make and strength of the locomotive or engine to which it is intended to be fitted.

In order to prevent the apparatus becoming overheated, when the feed is shut 06, there is an auxiliary pipe connecting with the boiler and direct to the upper chamber of the apparatus having a stop cock near the boiler, in order to admit of the free circulation of water from the boiler, back through the apparatus to the boiler again. Thus in effect the apparatus becomes part and parcel of the boiler when the feed is shut oif.

There is no back pressure on the exhaust of a locomotive or engine fitted with this apparatus, and entails no extra work or trouble to the d river, the difierence being that the cold water is first pumped or injected into the apparatus instead of to the boiler. The apparatus is constructed entirely of copper, and cylindrical in shape, having an upper chamber and a double row of vertical tubes connected to the inner sides of same, which take cold water from the upper chamber down the entire length of the apparatus, and are elbowjointed, and discharge to a lower chamber. The lower chamber extends to the bottom of the upper chamber. Both chambers entirely surround the tubes and form the outer casing of the apparatus.

The apparatus may be constructed of copper,in one or more parts jointed, or otherwise fastened, of any composition metal, and of any size. The tubes therein contained may be round, corrugated, twisted, or bent in any direction, in order to add to the heating sur: face. The use of this apparatus on any locomotive or engine will materially reduce the ordinary wear and tear upon a boiler, owing to the enormous saving in consumption of fuel.

In order that our invention may be more clearly understood, reference may now be made to the accompanying drawings, wherein comotive. same part.
